To all whom it may concern: 7

Be it known that'I, Lnvr DAMASKA, a citizen of the United State of Michigan, have invented certain new and useful Improvements in Heating Stoves, of which the following isa specifla cation.

This invention relates to improvements in heating stoves and has as its primary object to provide an attachment whichmay be arranged within the flue opening of any ordinary heating stove and which will serve to retard the passage of heated air currents and products of combustion from the stove to the flue so that a considerable portion of the heat which is ordinarily dissipated in passing up through the flue, is conserved by the aid of the invention. 1

Another object of the invention is to so construct the attachment that the heated air currents and products of combustion will be prevented from passing directly upwardly through the flue and will be caused, on the other hand, to takea path which will cause them to sweep in close proximity to the Walls of the stove before through the flue so that maximum benefit will be derived from the heat units radiated from the same.

In the accompanying drawing:

Figure l is a view partly in section and partly in elevationillustrating an ordinary heating stove equipped with the attachment, the latter being shown in vertical section;

Figure 2 is a detail. side elevation of the attachment removed from the stove;

Figure 3 is a horizontal sectional view taken substantially on the line 33 of F igure 2 looking in the direction indicated by the arrows.

In the drawing the numeral 1 indicates the body of a heating stove of an ordinary type, the numeral 2 the top ofthe body, and the numeral 3 the usual flue opening which is surrounded by the upstanding flange 4 over which is fitted the intake end of the flue or stove pipe 5. In this type of stove, the heated air currents and products of combustion ordinarily pass directly upwardly through the flue. 5 without being retarded in their course, and as a consequence a considerable portion of the heat is dissipated in the fiue and in the atmosphere when the gases leave the chimney, and it is to conserve this heat or a considerable portion thereof at least, that the States, residing at Cadillac, in the countyof lVexford andmetal or any other purpose and the same is passing outv Gare cut away,

The device em'b'o'd' prises a thimble which indicated in gen eral by the numeral 6' and which is of a" shape and "suitable dimensions to adapt it to be fitted be snugly thimble or down through the opening 8 and "body 6 maybe made of "sheet material suitable for the provlded exteriorly with a flange 7 which circumscribes its'upper edge, this flange being adapted to rest upon the upper edge of the device isin place, in the manner clearly shown in Figure l of the drawing, I the thimble is opening 3 and in proper alignment with the flue 5. The thimble 6 isfopen at its upperend and unobstructed interiorly from its per to its lower end except that at its lowerend it is partly closed by a battle plate which is indicatedby the numeral 8 and which is preferably of a marginal contour the same present invention de the flange 4, when contourof the thimble,

supported in place in the the stove, the device as a whole may be fitted downwardly through the opening 3 to assume the position shown in Figure 1'. The diametrically opposite sides asindicated by the numeral 9, so as to provide draft passages or openings 10 located abovethe opposite sides of the plate 8 and also so as to provide oppo-' sitely located depending supporting members 11 located between the openings 10 and having their lower end portions turned in-' wardly or flanged as at 12 and riveted or of the thimble otherwise secured as at 13, to the upper face of the plate 8.

It will now be evident that the bafile plate 8 is located a distance below the plane of the top 2 of the stove body so that heated air currents and rising from the burning fuel will be de 'fiected in all directions laterallyby coming products of combustion in contact with the under side of this plate s and thus be caused to pass in close proximity to the side walls of the stove body. The heated air currents and products of combustion will then sweep beneath the top 2 of the stove and will finally be deflected down wardly and about the thimble 6 and will lower end of the thimble ass out through the openings 10 and up through the thimble and finally through the flue 5. Being thus retardedin their passage from the stove through the flue however, the

heated air currents and products of combustion will transfer the major portion or their heat units. to the walls and'top of the stove body so that full benefit is obtained of these units which would otherwise be lost.

Having thus described the invention, what is claimed as new'is:-

A device of the-class described comprising a-thimble having a circumferential wall provided exteriorly at its upper end with a circumscribing flange projecting in an outward direction to seat upon the wall of the flue opening of a stove, the said wall at the being cut away at diametrically opposite sides to provide lateral passages and intervening depending supporting portions, said portions being bent inwardly toward each other and lying wholly within the bounds of said circumferential wall of the thimble, and a baitle plate secured to the under side of the said inturned lower ends of the supporting portions with its margin substantially flush with of said portions and lying wholly within the bounds of said wall whereby, the thimble may bebodily inserted in a downward direction into the flue opening of a stove and supported by said flange and may be bodily removed by upward dlsplacement;
